Q: “I will transit by air through Canada. Do I need an eTA?”
A: “Passengers transiting Canada will need an eTA or a visa, regardless of the length of time in Canada.”
And no, you must apply online, in advance.
The Government of Canada's official website to apply for an eTA to fly or transit through a Canadian airport. Find out what it is and how to apply online.
